Popoluca is a Mixe-Zoquean language of Mexico,
spoken by more than 30,000 people in the state of Veracruz. Actually there are four Popoluca languages, which are not
mutually intelligible: Sierra (Serrano) and Texistepec Popoluca are more closely related to Zoque, and Oluta and Sayula
Popoluca are more closely related to Mixe. Texistepec and Oluta are seriously endangered languages with primarily
elderly speakers remaining, but Sayula and Sierra Populuca are still being learned by children in Veracruz today.
